Answer:
0.15
Step-by-step explanation:
It's either 1050 or 1.050 if that was suppose to be a decimal or a comma after the eight
0.35x + 0.60y = 0.40(x + y) where x = vol. of 35% and y = vol. of 60%
x + y = 20
solve this system of equations
x + y = 20
-0.05x +0.20y = 0
this gives x = 16 and y = 4
so you need 16 L of 35% and 4 L of 60% solution.
